Hello there el Capitan!
Thanks for reaching out to us. So, let's dig in! with a 710 and good work experience, you are off to a good start. It's true that you do come froma somewhat tough demographic, but you do seem to have what it takes to make yourself a more original profile. I am especailyl curious about your family business. If its relatively large, this could be a BOON for you!
Otherwise I would definitely work hard to make your profile stand out, and I would also spread the risk of coming from such a tough candidate pool by applying to more schools.
As for which schools, with a 710 you can truly apply to any school you want. To give yourself a good chance, you will have to spread yourself out by applying to a few schools out of the top 10 too.
As for which schools specifically, that'll depend on your goals your location preferences, etc.
If you like the post, give it a KUDOS!
